feat(type-checking): disable type check by default (#4246)

Change the default of [`disableTypeChecks`](https://stryker-mutator.io/docs/stryker-js/configuration/#disabletypechecks-boolean--string) to `true`.

BREAKING CHANGE: `disableTypeChecks` is now `true` by default. You can use this configuration to opt out:

```json
{
  "disableTypeChecks": "{test,src,lib}/**/*.{js,ts,jsx,tsx,html,vue,cts,mts}"
}
```

This is needed because Stryker will create (typescript) type errors when inserting the mutants in your code.
